Re: Colorama, Americana, Scenic Prints

: : I have some prints in their original folers unframed. One is Colorama Prints Tintogravure by Stan Fenelle. Another is Scenic Prints Tintogravure by John Berkey. The third is Americana prints by Jon Arfstrom in TalioCrome. Any ideas of the value of any of these? TIA eu4bia
